Do I need new bolts or studs to install this?

Reuse your factory header bolts or studs — they work fine with this gasket. Tighten in a cross pattern to avoid warping, and refer to your vehicle's service manual for the correct torque spec.

What should I do to the gasket surface before installation?

Clean both the cylinder head and header mating surfaces with a wire brush or gasket scraper to remove all old gasket material and carbon buildup. A clean, flat surface prevents leaks.

Can I reuse my old header if I'm swapping in a new gasket?

Yes — this gasket pairs with both factory and aftermarket headers. Inspect your header's mating surface for cracks or warping before reinstalling. If the surface is pitted or uneven, have it resurfaced or replace the header.
